found a P74221 brand new and am thinking about using it as a helper pump with a raptor 150 on my 12 valve. I cant find anywhere what the operating pressure is for this pump. does anyone know?

thanks
 
I think this is a frame rail pump off a 2001.
The plan is to rig it up tk work off a hobbs switch and activate under boost to help maintain pressure.

It has one friend. This will be a helper that only activates on demand from manifold pressure.
